The invention is directed to an oil treatment apparatus and method for treatment of oil which transports oil to be treated from a source through a first conduit to a treatment station. The treatment station includes a filter system capable of extracting particulate material from the oil and removing the particulate material from the filter system as it is removed from the oil. The treated oil may then be transported for reuse, preferably in a continuous cycle with the source of the oil. A prefiltering system may be used to further enhance maintaining the quality of the oil and/or in efficiently treating the oil while accommodating throughput requirements. The prefiltering system may include a comminuter to reduce the size of larger particles in the oil, a coarse filtering system to remove larger particle, a system to introduce a treatment material to the oil or other systems to facilitate processing. The filtering system is designed to remove particles from the oil having a size of fifteen microns or smaller in the preferred embodiment.

1. A method of treating oil comprising the steps of:a) transporting a source of oil containing particulate materials to a treatment station, said treatment station including at least a filter system, said filter system being capable of continuously extracting said particulate materials from the oil

1. A method of treating oil comprising the steps of:a) transporting a source of oil containing particulate materials to a treatment station, said treatment station including at least a filter system, said filter system being capable of continuously extracting said particulate materials from the oil and removing said extracted particulate materials from the filter system,b) supplying said oil at a predetermined flow rate to said filter system and extracting said particulate materials of at least a predetermined size, andc) transporting said oil from said filter system,d) the method further comprising the steps of detecting if any objects which will not pass through said filter system are within said oil prior to supplying said oil to said filter system and shutting down operation of a pre-treatment stage of said filter system if any such objects are detected. 2. The method of treating oil as set forth in claim 1, wherein said step of extracting said particulate materials includes separating said particulate materials from said oil and deoiling said separated particulate materials prior to removal from said filter system to reduce the amount of oil retained in said removed particulate materials. 3. The method of treating oil as set forth in claim 1, further comprising the step of removing from said particulate material above a predetermined size prior to transporting said oil from said filter system. 4. The method of treating oil as set forth in claim 1, further comprising the step of comminuting said particulate material above a predetermined size in said oil in said pre-treatment stage prior to supplying said oil to said filter system. 5. The method of treating oil as set forth in claim 4, further comprising the steps of:detecting if any clogging of the treatment stage occurs and shutting down operation of said treatment stage occurs if a predetermined amount of clogging is detected. 6. The method of treating oil as set forth in claim 1, further comprising the step of introducing a predetermined amount of a treatment material into said oil prior to supplying said oil to said filter system. 7. The method of treating oil as set forth in claim 6, whereinsaid treatment material introduced into said oil is selected from the group consisting of diatomaceous earth material, fuller's earth material and activated carbon material.
